Been reading these forums forever, but finally made an account today. Was looking for a new set of IEM's to replace my SE530's (cable problem) a month ago and was deciding between these and the SE535 red limited editions as I've always wanted them. Bought a pair of UE900 from local apple store and they totally blew my mind. Thought the soundstage was more open, detailed, and found more extension in the low end than my SE530s. Already sold the SE530s so didnt have them to do A/B comparisons with. Used them for about 2-3 weeks and no issues with the cabling like some of you guys have here, but for whatever reason decided to return them and order the Red SE535's (probably more of a brand loyalty thing, since i've owned the e2Cs, SE210s, and SE530's). Nonetheless they are both great IEMs. Will probably buy another set of UE900s if the price ever drops. They are definately a step up from the Triple Fi.10s (which i also own).
